Acquisition 2.1 is Out
I'm not a big peer-to-peer downloader, in fact, I think I've downloaded just two things - a couple of Eddie Izzard tracks that we owned the DVDs for, but I wanted just the soundtrack. But when I needed to get that, I got Acquisition, and it's done a fine job for the limited used I've had for it. Today, I saw that they have released v2.1, and it includes Sparkle support and a few design tweaks and connectivity improvements.
So if you need something like this, I can say it works, but can't say it's all that much better than the other things out there. I just haven't had the need to look around that much.
